Title:

ELECTRIC LINEAR ACTUATOR

Document Type and Number:

WIPO Patent Application WO/2013/191066

Kind Code:

A1

Abstract:

This electric linear actuator is constructed with the inclusion of a threaded shaft that is supported in such a manner that the threaded shaft is unable to rotate with respect to a housing while allowed to move in the axial direction thereof. The housing comprises a first housing (2a) and a second housing (2b) that is butted to an end face of the first housing. A first void section (37), which is formed so as to have a substantially semicircular cross-section, and a second void section (37), which is connected to the first void section and formed so as to have a substantially triangular cross-section, are provided on the joint surfaces (35, 36) of the first housing (2a) and the second housing (2b) so as to face with each other. The first void section (37) is filled with a curable material (39) made of a silicone-based liquid gasket. The volume of the curable material (39) is set larger than the volume of the first void section (37) but smaller than the volume of the first void section (37) and the second void section (38) combined.
